https://devzone.nordicsemi.com/f/nordic-q-a/75507/mac-address-burning-on-nrf52840-moduleHi Team, We want to write our own MAC address on nRF52840 module. It&#39;s a production level MAC address i.e. it is fixed MAC address cannot be overwritten. What is the procedure I need to follow? Is there anything like OTP memory in nRF52840.
